Question

I cannot establish a connection between two players using auto-match and GKMatchmakerViewController.

The behavior is this:

1. didFindMatch is called

2. expectedPlayerCount is not zero (always 1)

3. didChangeState is never called

4. after an extended period of time the player disconnected is received.

Does anyone have a solution to this problem?

Thanks!

Answer 1

In order to get the correct number of players connected, make sure you setup your GKMatchRequest properly.

In this example, I have a game that only works if there are two players connected, so I set the min & max players count to 2:

GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = 2;
request.maxPlayers = 2;

GKMatchmakerViewController* mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
mmvc.matchmakerDelegate = self;

Then, everything you noted works as expected.

EDIT:

After reading your question again, also make sure you have retained the GKMatch object given to you by:

-(void) matchmakerViewController:(GKMatchmakerViewController*)viewController didFindMatch:(GKMatch*)match;

And of course, you have to set the delegate of this match object:

//Done!
-(void) matchmakerViewController:(GKMatchmakerViewController*)viewController didFindMatch:(GKMatch*)match{
    [self dismissModalViewController];
    [self setCurrentMatch:match];

    match.delegate  = self;

    if (!matchStarted && match.expectedPlayerCount == 0){
        matchStarted = YES;
        [delegate onMatchStart];
        self.handlerVoice = [OnlineHandlerVoice handlerWithMatch:currentMatch];
    }
}
